[comp.sys.atari.st] Blitter access!

870646c@aucs.UUCP (barry comer) (04/10/88)

If anyone has received information on how to access the blitter chip directly
could they please pass it on to me or the net. Actually any info on the blitter 
would be of interest(ie. just how much memory can it really move in a given 
time frame). I do have the blitter installed in my Mega 2, and have written 
some prgs. to measure improved flood fills, etc., but they do not tell the whole
story.

I would be interested in hearing about the blitter as well.

Some points of interest would be :
	o What sort of operations can it perform on its source and 
	  destination?
	o What are the memory alignment restrictions if any?
	o How do the Blitter and 68000 share the bus? 
	o What are parameters available to the blitter?
	o What does a blitter bus cycle look like?

I think there is definitely an article possibility here that I would
think would be very fun/interesting to write. Any info appreciated,
pointers are ok too.

These opinions are my own and no one elses, but you knew that didn't you.
